Rachel's place was quite a find for me. With this price range, it's unbeatable in the area. The (Ari and Sanam Pao) BTS stations are fairly close, and there is a 7-11 just a few mins walk from the house. The room was actually a bit bigger than I thought and quite stylish. She also has a few cleaning ladies working around the house who wouldn't mind cleaning the room for you. Her cats are quite friendly and pretty. If you love cat, this is definitely the place for you. Rachel is also very mindful of her guest.
The only downside throughout my stay is that they are building another house right next to this house. The construction starts at around 9am and finishes at around 5-6pm. You will hear a bit of hammering, but if you are outside during that time, you should be good. I expect the construction to be done in a month or two (around May 2018), but if you are concerned, you can definitely contact her first.
